As business consultant, I found SigmaNote helpful to get me up to speed on my research for client's work, insights, and presentations. It also helps me constantly update knowledge in that domain so save me lot of time to prepare my meetings with clients. And I can learn any subjects quickly and continuously. Overall it helps me a lot with my daily work and improves my productivity!

It is undeniable that "note-taking" is essential to our daily life and work. We take notes in notebooks, local files on laptops, and in the cloud. Day after day, we take a lot of notes, but organizing them is always a problem. Whether we are reporting to the team or preparing for an interview, or we just want to share the notes we have taken in the past with someone, but we can't find the notes we really need. As we step into the era of artificial intelligence, SigmaNote, a new app that claims to be driven by artificial intelligence, caught my eye, and after trying it a few times, I began to fall in love with it! SigmaNote has a simple and intuitive interface, and is supported by AI technology. It not only allows us to take notes easily, but also helps us organize all our notes intelligently, so that we can make better use of these notes anytime, anywhere. In addition, SigmaNote allows us to import PDFs, Office documents, web pages, YouTube videos, and even content shared from other apps, instantly merge with the notes we made, convert all into clean, editable Markdown notes that are very useful and power us with the "second brain" as they called. As an engineer who have touched so many software applications, I really like this app and I will continue to use it and recommend it to others!

Great product! SigmaNote stands out as a thoughtfully designed tool that blends simplicity with powerful functionality. Its clean interface, real-time collaboration, and seamless markdown support make it an ideal choice for note-taking, brainstorming, and technical documentation. Whether you're working solo or with a team, SigmaNote helps you stay organized and focused. I highly recommend it to anyone looking for a modern, efficient note-taking solution.
